실험 절차
To a solution of 3-(3,5-Dimethoxy-phenyl)-acrylic acid (12 g, 57.7 mmol) in EtOAc (100 ml) and MeOH (100 ml) was added carefully 10% Pd/C (1.3 g), the reaction mixture was shaken in Parr apparatus for 5 hs under 30-40 psi of hydrogen, then the solution was passed through a celite pad, the filtrate was concentrated and dried at 50° C. under reduced pressure to give product (11.7 g, 96.55%). LC-MS: m/e 209 (M−1)
